I am going to eat less than 100 g of carbs a day for the next week. What are the best alternatives to eat that have low amount of grams but are best in giving me energy and filling me up ?
There are ways you can reduce hunger without bumping up your caloric intake that much. For instance increasing your vegetable intake. Drinking lot of fluids. Eating foods that are higher in fiber etc.
It's all about volume when it comes to calorie-restricted diets.
